Abstract: In an embodiment, a method comprises causing, to be displayed to a user through a web page of a social network provider that provides a social network, contest data that indicates an online contest; receiving, at a particular entity, input that indicates an intention by the user to participate in the online contest; sending, from the particular entity, request data that indicates a request, by the particular entity, for one or more permissions that allows the particular entity to access information from the social network provider about the user; after sending the request data, receiving, at the particular entity, acceptance data that indicates that the user accepts the request; in response to receiving the acceptance data, causing the user to be entered in the online contest; wherein the method is performed by one or more computing devices.

Abstract: An object-oriented interrupt processing system in a computer system creates a system database including a device namespace containing an entry for each device in the computer system and an interrupt namespace containing an entry for each interrupt source, arranged as an Interrupt Source Tree. Each entry in the Interrupt Source Tree is cross-referenced to a corresponding entry in the namespace and contains a reference to an interrupt handler for the corresponding interrupt source. When an interrupt occurs, a single interrupt dispatcher is invoked, to access the Interrupt Source Tree and cause execution of the corresponding interrupt handler.

Abstract: A method and apparatus for providing memory functionality to object-oriented client software components of a computer system having a CPU using a first set of memory classes, each class of the first set being platform-independent; a second set of memory classes, each class of the second set being a subclass of a class of the first set and being platform-dependent; and performing client component memory functions by accessing only objects of classes of the first set. Descriptions of the classes and methods are provided, enabling platform-independent device drivers to be implemented.
